[SOLVED] I am not sure if this is a resistor, can anyone confirm if it is resistor?

If it is a resistor, what type of resistor is this?

And how can determine its watt rating?

Thank you.

It looks like a wire wound resistor. To get an idea of watt rating from its size, see the table in this link **broken link removed**

I agree a wire wound resistor. It should have its value printed on it somewhere if it has gone open circuit.

A wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance

I agree, definitely a power resistor. Somewhat odd that neither resistance nor power rating is tagged though.

It's a power tubular resistor from IRC. Have a look to thier web site.

Yup there is a tag saying it is 50W and 60ohms.

Can I use this wirewound resistor as a substitute?
Because this is the only available component near my area.

Thx for the many response and future reply.

It is wise to discuss the application to ensure inductance is not going to be a problem otherwise you need to order the Non-Inductive PN . If just a supply current limiter, then ok.

FYI
Non Inductive Resistor. To specify add N, e.g.: NHS50 56R J

 

[Circuitry Lab]

It will be used as a voltage limiter.
Is it the same as a current limiter?

Worth noting that the original is almost certainly an inductive type. If you use the metal cased one you found at RS, ensure you bolt it flat to the metal surface below it and ideally, use some heat sink compound to help with heat conduction .

[D.A.(Tony)Stewart]

It is worthwhile to note that non-inductive wire-wound inductors are bi-filar wound with current in opposite direction and look the same on the outside.

The application is that to make a new eddy current dynamometer from scratch. The use of the black wirewound resistor as a voltage limiter.
The NHS50 56R J will substitute the original (black) wirewound resistor in our new eddy current dynamometer.
